MASTER重新生成

为了模拟MASTER数据库坏了,我们就删除MASTER数据库(要停止SQL SERVER服务才能删除)在我的电脑,C:\ PROGRAM FILES\MICROSOFT SQL SERVER\MSSQL.1\DATE 中删除MASTER.MDF

重新生成MASTER

1.首先在CMD中输入

start /wait setup.exe /qn INSTANCENAME=<InstanceName> REINSTALL=SQL_Engine REBUILDDATABASE=1 SAPWD=<NewStrongPassword>

其中的 SETUP.EXE为启动光盘的路径,我这里的是 E:EXTUP.EXE /QN

我这里的为默认实例所以其中的<INSTANCENAME>用 MSSQLSERVER代替

最后的<NewStrongPassword>为密码我设密码为123,所以就用123代替<NewStrongPassword>

若没有返回错误,我们就可以到我的电脑中C:\ PROGRAM FILES\MICROSOFT SQL SERVER\MSSQL.1\DATE上面又有MASTER.MDF了

接下来的步骤和上篇一样

进入目录

单用户模式

启动SSMS工具,新建查询

搞上命令

启动服务

打开SSMS

连接到数据库后就可以发现数据库中的数据又回来了

以下是我在命令行下搞的命令,我用记事本的方式全部复制下来了,为了不传附件,我就直接粘贴到下面了

USE master
GO
RESTORE DATABASE master
FROM disk='C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Backup\master.bak'
GO

数据库中的显示应为

已为数据库 'master'，文件 'mastlog' (位于文件 1 上)处理了 4 页。
已成功地还原了 master 数据库。正在关闭 SQL Server。
SQL Server 正在终止此进程。
